Detailed implementation manners

[0041] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the present utility model in conjunction with the attached drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0042] In order to facilitate understanding of the prefabricated beam rainproof canopy provided by the utility model, its application background is first introduced. During the production process of prefabricated beams, especially in the concrete pouring stage, environmental factors can easily have an adverse effect on the quality of concrete. For example, when using a pump truck for concrete pouring, sudden rain may occur. Rainwater entering the concrete will affect the quality of the concrete, thereby adversely affecting the performance of the prefabricated beams.

[0043] In the related art, construction is generally avoided on rainy days to minimize the adverse effects of rain on concrete, but the above method will seriously affect the construction progress. Sometimes a temporary rain shelter is built for protection, but the construction and removal of the rain shelter is cumbersome, and the existence of the rain shelter will block the pouring port of the precast beam mold, affecting the layout of the pump truck delivery pipeline, which will have an adverse effect on the construction.

[0044] Therefore, how to conveniently and effectively realize the rain protection of prefabricated beams is an important issue that needs to be solved urgently.

[0045] In view of the above problems, the utility model provides a prefabricated beam rainproof canopy, which can conveniently and effectively realize the rainproof work of the prefabricated beam and ensure the construction progress.

[0046] Combine the following Figures 1 - 5 The utility model describes a prefabricated beam rainproof canopy.

[0047] Reference Figure 1 and Figure 2 A prefabricated beam rain shelter comprises a roof frame 10, a roof top layer 11 and support columns 12; wherein the roof frame 10 constitutes the top support of the rain shelter, and the roof top layer 11 is laid on the roof frame 10 to block the falling rainwater; a hoisting structure 13 is arranged on the top of the roof frame 10, and the hoisting structure 13 is used to be connected with the lifting equipment, and the support columns 12 are fixedly connected to the bottom of the roof frame 10 to provide bottom support for the rain shelter; a plurality of pouring openings 110 for the conveying pipeline of the pump truck to pass through are arranged on the roof top layer 11.

[0048] In a specific application scenario, when it suddenly rains during the pouring process or when constructing in rainy weather, the lifting structure 13 of the rainproof shed connected by the lifting equipment is used to lift the rainproof shed to the position where the precast beam mold is located. The support column 12 can provide bottom support for the rainproof shed, and the shed top layer 11 covers above the precast beam mold to block the falling rainwater, thereby reducing or avoiding rainwater from mixing into the concrete in the precast beam mold. The conveying pipeline of the pump truck can extend into the shed through the pouring port 110 on the shed top layer 11 to carry out the pouring work. When constructing on sunny days, only need to use the lifting equipment to lift the rainproof shed away from the precast beam mold. Compared with the related technology, the cumbersome erection and demolition work of the rainproof shed is eliminated, and due to the existence of the pouring port 110, it will not affect the layout of the conveying pipeline of the pump truck. Therefore, it can more conveniently and effectively achieve the rainproof work of the precast beam and ensure the construction progress.

[0049] It can be understood that, in order to facilitate the staff to carry out the pouring work, the size of the pouring port 110 can be slightly larger than the size of the conveying pipeline of the pump truck. In this way, during the pouring process, the staff can observe the pouring situation in real time through the pouring port 110. The rainproof shed can block most of the rainwater. Even if a small amount of rainwater seeps in through the fitting gap between the pouring port 110 and the conveying pipeline, since the amount of seepage is very small, it will not have a significant impact on the quality of the overall concrete.

[0050] The specific quantity and layout mode of the pouring port 110 can be designed according to the actual construction scenario, and no specific limitation is made in the embodiment of the present utility model. In addition, a protective door can be equipped on the pouring port 110. When the rainfall is too large and it is not suitable to continue construction, the pouring port 110 can be closed by using the protective door, so that the rainproof shed can effectively protect the concrete in the precast beam mold.

[0051] In some alternative embodiments, the protective door and the pouring port 110 are matched in a completely separable form, that is, when the pouring port 110 needs to be opened, the whole protective door is removed from the pouring port 110, and when the pouring port 110 needs to be closed, the protective door is buckled on the pouring port 110. The protective door and the pouring port 110 can also be matched in a form of being hinged on one side, that is, one side of the protective door is hinged to the shed top layer 11. When the pouring port 110 needs to be opened, the protective door is flipped open to one side, and when the pouring port 110 needs to be closed, the protective door is flipped and buckled on the pouring port 110.

[0052] In addition, when the protective door closes the pouring port 110, in order to ensure the stability of the protective door, the protective door and the shed top layer 11 can be connected by connecting components such as bolts, or can be locked by a lock such as a bolt-type lock.

[0053] Next, the structures of each component in the precast beam rainproof shed will be elaborated in detail with reference to the drawings.

[0054] Reference Figure 1 and Figure 3 Figure 3 , the shed roof skeleton 10 includes a frame 100, cross beams 101 and purlins 102; wherein, a plurality of frames 100 are arranged at intervals along a first direction, and in a second direction perpendicular to the first direction, the height of the top of the frame 100 gradually decreases from the middle to both sides; there are two cross beams 101 and they are respectively arranged on both sides of the frame 100 along the second direction, the cross beams 101 extend along the first direction, and a plurality of frames 100 are fixedly connected to the cross beams 101; the purlins 102 are fixedly connected to the top of the frame 100 and extend along the first direction, and a plurality of purlins 102 are arranged at intervals along the top curve of the frame 100 in the second direction.

[0055] Specifically, the above-mentioned first direction is the length direction of the rain shelter, the second direction is the width direction of the rain shelter, and it is also the length direction of the frame 100. In the second direction, the height of the top of the frame 100 gradually decreases from the middle to both sides, so that in the second direction, the shed top layer 11 presents a structure that is high in the middle and low on both sides. When it rains, the rainwater will fall along the shed top layer 11 under the action of gravity, which is beneficial to ensuring the drainage effect of the rain shelter and effectively avoiding the problems of water accumulation and water seepage from the pouring port 110.

[0056] The specific shape, structure and material of the frame 100 can be designed according to actual needs. For example, the frame 100 can be formed by welding square pipes, round pipes or other profiles. The top surface of the frame 100 can be triangular or arc-shaped. Reinforcing members such as diagonal braces can also be provided between the profiles to ensure the overall structural strength of the frame 100. In addition, according to the different sizes of the rain shelter, the length, the number of arrangements and the spacing between adjacent frames 100 of the frame 100 will be different, and specific ones can be flexibly designed according to actual needs, and no specific limitations are made in the embodiments of the present invention. The cross beams 101 are distributed on both sides of the frame 100 along the second direction and are suitable for connecting a plurality of frames 100 into a whole. According to different requirements, the cross beams 101 can be designed into different forms or structures. In this embodiment, the cross beam 101 is set as a rectangular truss structure, which can be formed by welding steel pipes, square steels or other profiles. The cross beam 101 of the truss structure has high structural strength and can greatly improve the stability of the shed roof skeleton 10.

[0057] The purlin 102 is laid on the top of the frame 100 to provide bottom support for the shed top layer 11. The specific material, arrangement quantity, spacing between adjacent purlins 102, and connection method between the purlin 102 and the frame 100 can be set according to actual requirements. For example, steel profiles such as square steel and C-shaped steel can be used as the purlin 102. The purlin 102 and the frame 100 can be fixed by welding, or can be connected by connecting members such as angle steel and bolts. In this embodiment, the purlin 102 is C-shaped steel, and the purlin 102 and the frame 100 are fixed by welding.

[0058] In order to further improve the structural strength, in one embodiment of the present utility model, referring to Figure 4 , the shed top skeleton 10 further includes connecting ribs 103 and reinforcing ribs 104; among them, there are multiple connecting ribs 103 arranged on the top of the frame 100. The extending direction of the connecting ribs 103 coincides with the top curve of the frame 100 in the second direction. And, the multiple connecting ribs 103 are arranged at intervals along the first direction. The connecting ribs 103 are fixedly connected to the purlin 102, and specifically, welding can be used for fixation. Through the multiple connecting ribs 103, multiple purlins 102 can be longitudinally connected into a whole, thereby improving the structural strength and stability of the purlin 102.

[0059] There are multiple reinforcing ribs 104. The reinforcing ribs 104 are arranged at an angle with both the purlin 102 and the connecting ribs 103 and are fixedly connected, and specifically, welding can be used for fixation. Through the reinforcing ribs 104, the integrity and structural strength of the purlin 102 can be further improved. In addition, multiple reinforcing ribs 104 can be arranged in a triangular shape or other stable geometric shapes to further improve the stability.

[0060] Specifically, the connecting ribs 103 and the reinforcing ribs 104 can be made of steel bars, or can be made of profiles with various cross-sectional shapes.

[0061] The structure composed of the purlin 102, the connecting ribs 103, and the reinforcing ribs 104 can provide stable support for the shed top layer 11. Specifically, the shed top layer 11 can be made of color steel tiles, or other materials can be used according to different requirements, such as composite boards, which are not listed one by one in the embodiments of the present utility model.

[0062] In order to further improve the structural strength of the rain shelter, referring to Figure 1 , the rain shelter further includes a diagonal bracing beam 105. One end of the diagonal bracing beam 105 is fixedly connected to the shed top skeleton 10, specifically, it can be fixedly connected to the frame 100 or the cross beam 101 of the shed top skeleton 10, and the other end is fixedly connected to the support column 12.

[0063] In one embodiment of the present utility model, referring to Figure 1 and Figure 5, the support column 12 includes a first support column 120 and a second support column 121; one end of the first support column 120 is fixedly connected to the shed top framework 10, and the other end forms a first docking end. One end of the second support column 121 forms a second docking end. The first docking end and the second docking end are detachably connected by a connection assembly 14. The inclined support beam 105 is fixedly connected to the other end of the shed top framework 10 relative to the first support column 120.

[0064] In practical applications, first, the second support column 121 is fixedly connected to a preset position in the beam yard, such as on the ground near the precast beam formwork in the beam yard, to locate the installation position of the rain shelter. Then, a lifting device is used to lift the rain shelter. The first docking end of the first support column 120 is docked with the second docking end of the second support column 121 and connected by the connection assembly 14 to achieve the lifting and installation of the rain shelter. With the split first support column 120 and second support column 121, the positioning and installation of the rain shelter can be facilitated.

[0065] In some alternative embodiments, the end of the first support column 120 can be fixedly connected to the cross beam 101 of the shed top framework 10 or to the frame 100 of the shed top framework 10. The connection method can be welding or can use connection members such as bolts for connection. Specifically, it can be selected according to actual requirements and application scenarios.

[0066] The connection assembly 14 includes a first flange 140, a second flange 141, and a connecting member. Among them, the first flange 140 is fixedly connected to the first docking end, the second flange 141 is fixedly connected to the second docking end, and the connecting member is adapted to sequentially pass through and connect the first flange 140 and the second flange 141. Specifically, the connecting member can use a bolt.

[0067] To facilitate the positioning of the first flange 140 and the second flange 141, the connection assembly 14 further includes a positioning protrusion 142 and a positioning opening. The positioning protrusion 142 is connected to the end face of one of the first docking end and the second docking end. In the direction away from the first docking end or the second docking end, the cross-section of the positioning protrusion 142 gradually shrinks. The positioning opening is arranged on the end face of the other of the first docking end and the second docking end for plugging and matching with the positioning protrusion 142.

[0068] When installing the rain shelter, first fixedly connect the second support column 121 to the preset position of the beam yard to determine the installation position of the rain shelter. Then, use a lifting device to lift the rain shelter. The first docking end of the first support column 120 is docked with the second docking end of the second support column 121. Since the cross-section of the positioning protrusion 142 gradually shrinks, the positioning protrusion 142 can be conveniently inserted into the positioning opening and guided, realizing the quick and accurate docking of the first flange 140 and the second flange 141. Then, use a connecting piece to connect the first flange 140 and the second flange 141 to realize the connection between the first support column 120 and the second support column 121.

[0069] Specifically, the positioning protrusion 142 is arranged on the end face of the second docking end, and the positioning opening is arranged on the end face of the first docking end.

[0070] Specifically, the positioning protrusion 142 is in the shape of a frustum of a cone, and the first support column 120 is a steel pipe with an open lower end, so as to form a positioning opening at the first docking end of the first support column 120.

[0071] In an embodiment of the present utility model, a connecting plate 122 is fixedly connected to the other end of the second support column 121 relative to the second docking end. The connecting plate 122 is used to be attached to the ground and fixedly connected to the ground through connecting members such as expansion bolts.

[0072] In order to ensure the stability of the lifting of the rain shelter, in an embodiment of the present utility model, referring to Figure 4 , a plurality of lifting structures 13 are uniformly arranged around the geometric center of the rain shelter. In this way, when the rain shelter is lifted, its center of gravity is located at the geometric center, ensuring the balance of lifting.

[0073] Specifically, the lifting structure 13 can adopt a lifting ear welded to the top of the roof skeleton 10.

[0074] Of course, the lifting structure 13 includes but is not limited to the structures or forms listed above. In order to improve the stability of lifting, other structures or forms of the lifting structure 13 are also applicable.

[0075] It can be understood that, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0076] Through the precast beam rain shelter provided by the utility model, when it suddenly rains during the pouring process or when construction is carried out in rainy days, the lifting equipment is used to connect the lifting structure 13 of the rain shelter to lift the rain shelter to the position where the precast beam mold is located. The support column 12 can provide bottom support for the rain shelter, and the top layer 11 of the shelter covers above the precast beam mold to block the falling rainwater, thereby reducing or avoiding rainwater from mixing into the concrete in the precast beam mold. The conveying pipeline of the pump truck can extend into the shelter from the pouring port 110 on the top layer 11 to carry out the pouring work. When construction is carried out on sunny days, only need to use the lifting equipment to lift the rain shelter away from the precast beam mold. Compared with the related technology, the cumbersome erection and demolition work of the rain shelter is eliminated, and due to the existence of the pouring port 110, it will not affect the layout of the conveying pipeline of the pump truck. Therefore, the rain protection work of the precast beam can be realized more conveniently and effectively, and the construction progress can be guaranteed.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
